"It's about how quickly (how many operations per second) it takes to initially transfer data where the performance gain for random reads is a factor of 150! "
Bizarre. I have never wondered if I could speed up my IOPs by a factor of 150 to begin playing a music track any faster from my HDD based NAS. I hit play and the music plays immediately. I hit Skip and it Skips instantly.
By your description your HDD based NAS setup must have been pretty clunky. Glad that you fixed it with the SSDs.
P.S. IOPs translate to MB/Sec and the other way around. It's also based on block size. You can Google it and do the math but again, tweaking these figures is irrelevant to a properly working NAS for music playback. Maybe its your music server software that's to blame as the demands for music playback are extremely low unless there's something wrong with the setup.
